Hey guys, first post on this site.
A couple times now I’ve had a strange problem happen in my 2008 Ford Taurus X. Driving at cruising speeds (50+), the car’s engine light, airbag light, TPM sensor will all come on and stay on for a few minutes. Also, the speedometer will zero out and the transmission will seem to shift to a higher gear. When this happened yesterday, I had to move a few lanes over (rush hour, I-95) to try and get to the side of the road. By the time I worked over two lanes, the problem was gone. The same thing happened today, and I figured it’d go away in a couple minutes, so I kept driving. It didn’t go away, so I pulled over and turned the engine off. When I restarted the engine, the problem went away, but the car was still in the higher gear, so it lugged along the side for a second until it reached 20 mph to merge and then shifted roughly and is apparently now driving fine. My first thought is that I have a bad speed sensor, any ideas what the problem could be?
